QUICK HELP! WILL AWARD BRAINLIEST

For Question 1, Ideas that are Science based, are often testable, verifiable, can be falsified, and based on evidence.

Ideas that are non-science based are not testable, not verifiable, said to be infallible and are based on belief.

For Question 2, The gravitational force increases as the size of an object increases. On the other hand, the strength of gravity is inversely related to the square of the distance between two objects.

For Question 3, The equation from density is mass over volume.

Changes volume it will change by a inverted proportion. Increases it will decrease the density, decreasing it wil increase the density.

Changes mass it will change directly. Increasing mass it will increase density and vice versa.

For Question 4, Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density.

For Question 5, I'd say it's for proof of their theory.

Hope this helped.

kati45 [8]

Answer:

Two European men and two Polynesian women settled on a previously uninhabited tropical island. All four of the settlers have brown eyes, a dominant trait, but one of the Europeans is heterozygous and carries the recessive gene for blue eyes. No new settlers arrive,and nobody leaves the island.After a few generations,the percentage of blue-eyed individuals increases from the original zero to 25 percent.This is probably due to which of the following factors?

genetic drift

Explanation:

Genetic drift entails when there are changes in the gene frequency which occur in a gene that is existing. From the analogy above, it is a known fact that only gneetic drift could allow such to happen as mutation will only occur with a sudden change of gene which is not the case described above
